Superior Energy Efficiency

Edit

One of the hallmarks of a quality home or commercial building is a tightly-sealed, well-insulated structural shell. Usually, insulation fails because gaps and cavities along the walls or roof allow interior conditioned air to escape while also permitting unconditioned air to infiltrate the structure. The Insulspan SIP panel system provides a continuous core of solid expanded polystyrene (EPS) insulation. This means it does not sink like fiber batting or shrink over time like spray foam. When the conditioned air inside your home is prevented from leaking out, you not only save money by re-conditioning that air, you live in more comfortable interior spaces.

Edit

How does an airtight building system using Insulspan SIPs improve one’s comfort? First, the higher R-value achieved with SIPs, versus that of stick built construction and traditional batt insulation, means buildings experience less heat loss. This same higher R-value also results in less leakage of conditioned air. Maintaining a consistent temperature throughout a home or commercial building increases occupant comfort.

SIP building envelopes also perform well in blocking and absorbing sound. This sound absorption or blocking includes high frequency noises that often impact one’s quality of life. Spaces built with Insulspan SIPs airtight building envelopes are oftentimes so quiet, owners and occupants refer to them as sanctuaries.

Edit

The biggest threat of water damage in your home comes from vapor. Vapor naturally wants to move from the warm side of a wall to the cold, and in order to reach its target, the vapor will pass through your walls in a process called diffusion.

As the vapor moves, or diffuses, through the home’s walls, it can reach a dew point which results in condensation. Condensation needs a plane, or surface, on which to gather. The cavities within a traditionally-framed wall offer a plane on which the condensing moisture will accumulate. This condensation can result in damage to your home, including rot and mold.

A key advantage of SIP walls is that there is no place for the water vapor to condense. Insulspan SIPs have a continuous bond between the OSB and EPS, therefore they do not have pockets for the moisture to settle. As a result, the vapor continues right through to the other side of the wall.

Edit

Healthy interior environments are important no matter what the building’s purpose. SIP building envelopes create healthier buildings from the inside out. Insulspan SIP-built buildings result in airtight building envelopes, minimizing or eliminating incoming unfiltered air. This means homeowners and commercial building occupants enjoy improved indoor air quality. Just how healthy are SIPs?

The expanded polystyrene (EPS) insulation and oriented strand board (OSB) used in the manufacture of Insulspan SIPs meets some of the most stringent standards for indoor air quality.

Our SIPs do not off gas, and do not contain any volatile organic compounds (VOCs), chemicals that can adversely affect the health of an occupant.

Many contaminants, toxins, and other allergens are filtered out of the home. This is because the combination of the air-tightness of Insulspan SIPs and a properly-sized HVAC system creates a healthier building from the inside out.

SIP Construction

Edit

SIPs have structural properties similar to that of a steel I-beam. This is because Insulspan SIP systems consist of solid core, pre-cut SIP panels manufactured to your exact computer-drawn specifications. The rigid insulation core of the SIP acts as a web and the sheathing function as flanges. The continuous structural lamination of the EPS insulation to the OSB offers strength and resistance to impact. In fact, SIPs have proven performance during extreme weather conditions and natural disasters such as hurricanes, tornadoes, and earthquakes.

Structural roof sections and floors also use SIPs. Our comprehensive ready-to-assemble system approach to the construction of your structure is what distinguishes us from the competition.

Edit

While the Insulspan SIP system enhances structural strength and structural durability, SIPs additionally offer superior design flexibility. The composition of the laminated performance-rated oriented strand board (OSB) allows buildings to be designed using less dimensional lumber. And, because SIPs can span large distances, interesting and unique design opportunities are available for homeowners and architects to explore.

Because of the size and strength of SIPs, a significant expanse in a structure can be spanned. In turn, more design flexibility in those spaces exists than with traditional stick framing.

Edit

Insulspan SIP manufacturing uses a quality management system (QMS). We start with detailed drawings, using exacting specifications from our design team. Those specifications are sent to our CNC machines, resulting in precisely cut panels for your project.

Our quality construction process also helps you on the job site. An Installation Guide and assembly details are available for reference. In addition, we offer the services of an on-site advisor, if desired. The result? Decreased subcontractor costs, and a longer lasting, higher quality structure.
